United Abrasives grinding resin bonded mounted points are made from aluminum oxide grain.  Use for deburring and finishing ferrous metals such as iron, steel and welds.  Unlike vitrified abrasive grinding mounted points, the resin bonded points are also fast stock removal.  These mounted points are a low cost alternative to carbide burrs and are dressed for perfect balance to perform without vibration or run-out.  This part number is a Type "A" shape designed for offhand applications.  3/4" diameter, 2 1/2" length and 1/4" shank.  For die grinders.
